Although FIGS. 5A, 5B, and 5C illustrate that a display 520 has an area that is smaller than that of a PCB 530, for convenience of description, the present disclosure is not limited thereto. For example, the display 520 may have a form or size that is the same as or similar to that of the PCB 530. As another example, although FIGS. 5A, 5B, and 5C illustrate that an outer housing 510 has a specific interval with the display 520 or the PCB 530, the outer housing 510 may be arranged close to the display 520 or the PCB 530, or may be attached to the display 520 or the PCB 530.

Referring to FIG. 5A, an electronic device 501 may transmit and receive a multiband frequency signal by using at least some of an outer housing 510, a display 520, and a PCB 530.

As another example, if the distance is shorter, a frequency single of a relatively high frequency band may be transmitted and received. According to various embodiments, in the electronic device 501, the length of a first route (a route that, starting from a feeding point 551 a of the PCB 530, includes a first conductive member 551, a radiator 511 of the outer housing 510, a second point 510 b, a second conductive member 552, and a ground point 552 a of the PCB 530) may be an electrical length of a radiator that is operated as a multi-loop antenna.

The display 520 according to various embodiments may be connected to the ground part 554 a of the PCB 530 through the fourth conductive member 554 (a second electrical path) and a ground point 554 b of the display 520. The connection may prevent the adjacent display 520 from acting as an electric wave interrupting factor in an operation of transmitting and receiving a signal to and from the PCB 530.

According to various embodiments, referring to FIG. 5B, the electronic device 502 may have a form in which the display 520 is closer to the outer housing 510 (or the first conductive structure), unlike in FIG. 5A. In order to guarantee the portability of the wearable device, the entire thickness of the electronic device 502 may be smaller and a distance between the first conductive structure and the display 520 may be shorter.

For example, the first conductive structure (a conductive material part of the outer housing) 510 may be formed in a side wall of the electronic device 101, and may have a height that is the same as or similar to that of the display 520 in a forward direction (direction a) of the electronic device 101. The first conductive structure may surround the display 520.

According to various embodiments, the electronic device 502 may have operational characteristic similar to those of the electronic device 501 of FIG. 5A, but may show different resonance characteristics in some bands. The electronic device 502 may be designed to transmit and receive signals of a necessary frequency band by adjusting a distance between the first conductive structure and the display 520, a location of the ground part, or the like.

According to various embodiments, referring to FIG. 5C, in the electronic device 503, the second point 510 b and the third point 510 c of the outer housing 510 may be connected to a ground area (or a ground member) of the display 520, unlike in the electronic device 501 or 502.

The third conductive member 553 may connect the third point 510 c and a ground connecting point 553 b of the display 520 (a third electrical path). The electronic device 503 may have resonance characteristics that are similar to those of the electronic device 501 or the electronic device 502, but may show different resonance characteristics in some bands.

Meanwhile, operational characteristics of the electronic devices 501 to 503 may vary according to the type of a connected ground part (for example, a ground area of the display 520 or a ground part of the PCB 530) or a distance (or an arrangement form) between the first conductive structure included in the outer housing 510 and the display 520 at some frequency bands. According to various embodiments, the electronic devices 501 to 503 may transmit and receive signals of a first band 561 (for example, a band of 700 MHz to 900 MHz) and a second band 562 (for example, a band of 1600 MHz to 2400 MHz). The electronic devices 501 to 503 may be set such that the resonance characteristics thereof at the second band 562 that is a high frequency band are the same as or similar, and may be set such that resonance characteristics thereof at the first band 561 that is a low frequency band vary according to the type of the ground part, and a distance between the first conductive structure and the display 520. For example, when the electronic devices 501 to 503 correspond to the graphs 570 to 590, respectively, the electronic device 502 may transmit and receive signals of a frequency band that is lower than that of the electronic device 501 at the first band 561. A distance between the outer housing 510 (a first conductive structure included in the outer housing 510) and the display 520 of the electronic device 502 may be shorter than that of the electronic device 501. In the electronic device 502, a performance of the antenna of the outer housing 510 may deteriorate due to the approach of the display 520, and an influence by coupling may increase.

According to various embodiments, the electronic device 503 may transmit and receive frequency signals of a band that is higher than that of the electronic device 502, at the first band 561. Unlike in the electronic device 502, in the electronic device 503, a plurality of ground connectors having the first conductive structure may be connected to the display 520.
